12 cm yo the approximate square in each individual variable
I'll just do red for now, but if you're very desperate I guess I'll help with a few more lol. It's just a lot of typing and my computer is at 6% :)
RATIO:
Ratios are another way of comparing things. It's almost like a fraction, except that it can look like x:y.
I'm guessing you're comparing all of the reds to the total amount, which should be 39. Put 5 in for x and 39 for y to make it look like 5:39.
DECIMAL:
Oh decimals are so fun...
Just divide 39 by 5. The answer to red's decimal is 7.8.
PERCENTAGE:
Percentage can come a little bit confusing to some people, so I'll explain this the best I can.
Basically, all you have to do to find it is divide the number you're making into a percentage by the total amount, then multiply it.
5/39 x 100
0.1282051282 x 100
12.8205128205
I'm going to the nearest hundredth which is 12.82.
Your percentage is %12.82
(If you're rounding to the nearest whole number, it'll be %13)
THEORETICAL:
For this simplify your ratio. 5/39 cannot simplify, so just leave it as 3/39.
Sorry, sometimes I come out a little confusing, so just try not to think too hard about what I'm trying to say if you're confused more lol. Anyway my computer is going to die so I'll go now :)
Answer:
32 5/8 (or 32 and 5/8)
Step-by-step explanation:
Okay, so this problem is asking for us to solve this problem with the substitution of a variable: x = -4. Before we fully solve this problem, we need to replace all of those x variables with -4 so that it is easier to solve.
-7 1/4(-4) + 3 5/8.
To make this problem even easier to solve, let's turn these mixed numbers into improper fractions. To do this, multiply the denominator by the whole number. Then add the numerator to this number. The new number that you just got is now your new numerator for this number.
-29/4(-4) + 3 5/8.
Repeat the last step to turn the other mixed number into an improper fraction.
-29/4(-4) + 29/8.
Now let's multiply that -4 by 29/4. Because a whole number technically has a denominator of 1, we can now set up the next part of our problem. (The symbol * means multiplication since we can't use x since it is already being used as a variable in this equation.)
(-29/4 * -4/1) + 29/8.
29 + 29/8.
Now to solve the rest of this problem, let's convert the whole number of 29 so that it has a denominator of 8. This is that these two numbers are addable.
<u>29</u> x <u>8</u> = <u>232</u>
1 x 8 = 8
Now these numbers are addable. So:
232/8 + 29/8 = 261/8 = 32 5/8.
I hope that this helps.
